WINDMILL.

SPECIFICATION forming part of Letters Patent No. 258,826, dated May 30, 1882 Application filed April 8, 188:2. (No model.)

' a citizen of the United States, resident of Greenwood, in the county of Cass and State of N ebraska, have invented a new and valuable Improvement in Windmills; and I do hereby declare that the followih g is a full, clear, and

exact description of the construction and oper-- ation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side View of my windmill, and Fig. 2 is a perspective view of the sail.

This invention has relation to wind-engines for pumping water, and other purposes involving a similar movement; and it consists in the construction and novel arrangement of the horizontally-pivoted vibrating sail, the vertically-vibrating lever to which it is pivoted, the reversing-stops, and the rotating stem carrying said lever; and the invention also consists, in connection with the rotary stem, vertically-vibrating lever pivoted thereto, and the vertically-vibrating sail pivoted to the lever, of the pivoted lever-stops and the operating-crank connected thereto, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the supportin gframe-fwork or tower, having a pivot-bearing, B, on a crossbar, O, for the foot of the stem D, which extends upward through a guide-opening, E, in the platform F. Pivoted to bearings on the platform are the lateral bearing rollers or wheels 9 g, which are designed to facilitate the rotary movement of the stem.

G represents a vertically-vibrating lever or working-beam, pivoted on a horizontal fulcrum, h, at the upper end of the stem D. To one arm of this lever or beam is pivoted the vibratory sail H, and to the other arm is connected a weight, k, which is designed to counterbalance the weight of the sail and its attachments. The sail H is designed to vibrate vertically on its pivot-bearing 1, whereby it is connected to the end of the arm of the lever G. The sail extends in rear of as well as in front of the pivot-bearing but-the portion H in front or' toward the wind is designed to be longer than the part in rear, so thatits leverage may be greater. The sail may be pivoted between the branches of a forked arm of the lever; or, as illustrated in the drawings, it may be centrally slotted from the pivotal part forward through the edge, as indicated at m, to

accommodate a centrally-arranged lever-arm,

so that the vibrations of the sail and the vibrations of the lever will be mutually unobstructed. The sail is designed to be provided with vertical vanes K, which serve to keep it in the wind, the entire machine rotating as the wind changes on the pivot-bearing of the stem.

To the lever G are connected stops 8 ands, respectively arranged above and below the front portion of the sail in such position that they will limit the vibratory movements of the sail, turning it downward and forward to catch the wind on its upper side when it has lifted the lever-arm sufficiently high, so that it then reverses its movement, depressing the leverarm until it is turned upward and forward by the lower reversing-stop to take the wind on the under side, and again lift the arm of the lever. Corresponding movements of the weightarm of the lever are, by means of a pitman-rod, P, pivoted thereto, communicated to the plunger-rod of a pump.

In order to regulate the vibratory movement of the lever, pivoted or lever stops are employed, arranged in connection with bearings 70 on the lever-beam G, and having connections 6, extending to the arms m of a crank-shaft, a, pivoted in bearings on the stem D, and operated by means of a cord, wire, or chaimz, attached to an arm, m of said crank-shaft. By means of the operating cord or wire 2 the distance between the stops 8 and s can be diminished, thereby lessening the play of the sail and limiting the vibratory movements of the lever-beam in regard to their extent. The

rapidity of the action of the lever-beam can also be regulated by these stops, and if necessary the action of the beam can be stopped.

A swinging lever, vibratory fan, a bar, and a cord have been combined in a wind-engine, and I make no broad claim to such a construction herein.

Havingdescribed thisinvention,whatIclaim, and desire to secure by Letters Patent, is-= 1. In a wind-engine, the rotary stem D, the vertically-vibrating lever-beam G, pivoted thereto, the vertically-vibrating sail H, pivoted to an arm of the lever-beam, and the reversing-stops s and s, substantially as specified.

2. A vibrating wind-engine consisting of a rotary stem in bearings, a vertically-vibrating lever-beam pivoted thereto, a vertically-vibrat- 10 ing sail, pivoted to an arm of said lever-beam,

and pivoted lever-st0ps arranged to engage and reverse the sail and limit the movements of the lever-beam, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence I 5 of two witnesses.
